A drive device for electric vehicles comprises a casing, a motorhoused in the casing and having a rotating shaft, a housingrotatably fitted around the casing and coupled to the outer end of the rotating shaft of the motor by a reduction gear mechanism, a drive wheelprovided around the housing and an electromagnetic brakefor arresting the rotation of the rotating shaft of the motor at the base end of the shaft. The rotating shaft of the motor is engaged with or disengaged from the electromagnetic brake by a clutch mechanismprovided between the shaft and the brake.

The invention provides an electrically movable vehicle drivable by a simplified mode of control and a control program for driving the vehicle. A normalized value Y' representing translation motion and a normalized value X&#x2032; representing turning motion are fed from a command value input unitto a velocity command value calculating unit. The calculating unitdetermines a translation velocity command value Vbased on the normalized value Y&#x2032;. The calculating unitdetermines a turn angular velocity command value &#x3c9;that will always satisfy Expression (2&#x2013;4) for preventing the vehicle from falling down. The translation velocity command value Vand the turn angular velocity command value &#x3c9;determined by the unitare fed to a control command value calculating unit, which calculates control command values for left and right drive wheels. The control command values are fed to a motor control unitto control motors Mr, Ml and control the drive wheels.

In accordance with the present invention, there is provided a water treatment system for sterilizing water retained in a water container. The system includes a circulation process line for pumping the to-be-sterilized water out of the water container, sterilizing the water through electrolysis, and feeding the sterilized water back into the water container; an arrangement for producing a sterilizing solution having a sterilizing function by electrolyzing an electrolytic solution containing chlorine ions and having a function of promoting an electrochemical reaction; and an arrangement for supplying the produced sterilizing solution into the circulation process line as required. The system can constantly sterilize the water in the circulation process line and, as required, additionally supply the sterilizing solution produced by the sterilizing solution producing arrangement into the circulation process line according to a variation in the quality of the water.

A washing machine according to the present invention is a new washing machine which is compact and can realize uniform and good washing. The plane shape of a washing tub 211 is an approximately rectangular inner shape which is defined by a bottom 213, a pair of long side walls 214a and 214b, and a pair of short side walls 215a and 215b. A pulsator 212 is so provided on the one long side wall 214b out of the pair of long side walls that its center axis 219 is perpendicular to the long side wall 214b. The diameter A of a disk 220 of the pulsator 212 is so set that W&lt;A. Further, a projection 221 of the pulsator 212 is a projection which is long in the radial direction of the disk 220, so that the height thereof from the surface of the disk 220 is large on the side of the circumference of the disk 220. In the washing machine, the pulsator 212 is increased in the efficiency of agitation of wash water and laundry in the washing tub 211 while being longitudinally arranged.
